    Importing HDCam files

    I am having problems importing HDcam 720P footage into XE.

    I was given the files complete structure from the camera on to a Hard drive.

    When I Xrecieve the .mxf files they come in either Copy or Link, but they are between 5 and 15 seconds short.

    There is no sequence to the time cut off. If I import them using normal "Import Media" it's the same but different durations of clip.

    They play okay but the entire clips do no come in, the longest clip is only 30 seconds.

    What am I doing wrong?

    Re: Importing HDCam files

    Hi Mark,

    How were the clips transferred from tape to hard drive? ....and what (NLE) did your client use for the transfer? I'm presuming that you can see the entire (correct) clip duration using some other player, so you can confirm that it is actually "all there" etc

    Usually if we are using straight MXF files (on a hard drive) created from something like HDCAM, we just "import" them like a normal clip. We use Xrecieve for file-based formats such as XDCAM/HD etc which have an XML file along with the HD and proxy files..... and to be honest, we've never worked in 720P, only 1080i/p. We've never (touch wood) struck a problem with truncating files.....

    Hi Roger,

    The cameraman transfered them from camera to a prortable hard drive through his laptop.

    It is XDCAM/HD, and I can see all the file structures on the hard drive, XML files etc.

    And yes if I use Sony Player I can see all the complete pictures.

    So not sure what is going on?

    Re: Importing HDCam files

    ...are you saying that only 30sec comes in or the longest clip you need to import is 30 sec??

     Went and double-checked the files that we use.. Looks like we've been using footage shot in an F355... so that would make it 1440x1080 @ 35Mb/s... Haven't used anything from the '700 or '800 within Liquid... If you're interested, maybe you could upload a small clip to our FTP and I'd be happy to take a look to see what we can work out for you...

    Re: Importing HDCam files

    This sort of sounds like the problem with the Sony clip browser program to convert mp4 to MXF files.  Even if those cameras were not used it does sound like a similar problem that users have with the newer version of the clip browser.  If this is a newer camera then it may make sense that how they write the MXF file is similar to how they do it with the newer clip browser.  You may be able to find an old version of the clip browser to strip out the mxf files into new mxf files that are known to work in Liquid.

    Is this the newer 4:2:2 flavor of XDCAM?

    Re: Importing HDCam files

    Roger,

    It was shot on a 700, at 1220 x 720 50p 35Mb/s Pal. I would like to try to upload a clip to you, would you need the whole file structure?

    Smetvid,

    I had similar thoughts, I have been using Clipbrowser 2.0 only because of the fault with later versions, however I don't seem to be able to see the .mxf in clipbrowser to be able to try and convert to new .mxf.

    Any idea when your new transfer tool might be ready? I'll pay!!

    Just as a work around I've done for now, I was given the latest version of Sony Vegas Pro 9.0, It saw the clips I put them on to a 1440 x 1080 timeline, rendered them out, printed to a HDV tape, so I could get them in to Liquid at half decent quality to work on.

    Thanks Guys

    Hey Mak,

     Okay, I;ll be back in the office tomrrow morning.... I'll set access to our FTP... lets take it one step at a time and see if we can come up with something that works for you...

    Like Thomas says, some of the problem could be being caused by the newer versions of Sony's clip browser.... I'll have a "play" and see what we can come up with...

    Re: Importing HDCam files

    Hi Mark,

    Seeing the same thing here - truncated clip.... The XML data shows that the clip was captured on a '700 XDCAM HD at a frame rate of 50P. Any reason why you shot at 50P as opposed to either 50i or 25P? Personally, I think that may be the problem. Liquid can handle 25P on the timeline (and yes, the part of the clip that we can see plays fine in both the preview and line monitor), but I'm not sure about importing or Xreceive for 50P..... All I know is that we regularly import and Xreceive both 25P and 23.98P and Liquid handles them without a problem...

    ....so, not much help I'm afraid....Embarrassed

    Re: Importing HDCam files

    Mark,

     Just tested the file on our Media Composer system (V3.5.4).... works fine.... sees the whole clip, (timeline is a 720 50P timeline...) so it's definitely something a little out of the ordinary for Liquid to handle... but hey, considering that 50P wasn't even on the horizon when the last Liquid update came out, we should probably be surprised that we're seeing anything at all on it!

    Cheers!

    Re: Importing HDCam files

    Yes, thanks Tomas... Actually have 4.0.3 here but I'm reluctant to update mid-project. I know it's usually not a problem to update, but I don't want to tempt fate! Wink

    At least it showed that there wasn't a problem with Mark's file!...

    Re: Importing HDCam files

    It was my understanding that Liquid (all flavors), could not X-Receive 720p Files, only 1080i....    was somewhere in the Notes if I remember correctly.  Is this not the case?

    And, the "bitte" please take a look at the Vectorscope Issue and give a little feedback please. (sorry for the Hijack)

    Cheers

    Re: Importing HDCam files

    Okay, thanks Jeff... did not know that about the 720p files... fingers crossed for Nextgen....

    I'll have a look at vectorscope problem a.s.a.p.

    Thanks again for the input...

    Re: Importing HDCam files

    The 720p limit was for DVCPROHD and not mpeg2 flavors of video.  720p works perfectly in Liquid.  720p 50p and 60p are industry standard broadcast formats and are fully supported under Liquid.  In fact if you work with uncompressed 720p and Chrome you can only capture as 50p or 60p.  Have any of you tried importing the MXF files instead of X-receiving them?  I have never used X-receive and I always prefer to just import the material manually.

    Re: Importing HDCam files

    Smetvid,

    I have tried importing the .mxf files the normal way, and the files are still truncated and the strange thing is that the length is not always the same as with the Clipbrowser 2.5/2.6 .mxf EX3 problem.

    With that problem ever clip is only 9.15 long, this problem gives different lengths.

    Any news on your "Browser"?

    Roger,

    We shoot 720 50p, because we have to supply our TV commercials as SD on a IMPEG-2 422p@ML (m2v) timeline. then we use Omneon to encode a file to upload the commercials to London, and 50p downconverts on a timeline better than 50i or 25p...unless you know of few settings I don't know about?

    The BBC have done a few white papers on down converting HD files to SD especially with EX3 cameras, which we normaly use, and they recomend 720 50p.
